' SPECIFICATION forming part of Letters Patent No. 355,732, dated Januarykll, 1887.

' Application filed January 26, 1886. Serial No. 189,787. (No model.)

To vall whom it may concern:

Be it known'that I, GEORGE W. SwETT, of the village of Lansingburg; county of Rensselaer, State of New York, have invented new and useful Improvements in Oil-Stoves, of which the following is a specification. y

My invention relates to improvements upon the tanks or Oil-supply chambers of oil-stoves; and my invention consists, as will be more fully detailed hereinafter in connection with itsl illustration, in the combination, with a feedopening connecting with the tank or oil-supply chamber of an oil-stove, of a sight-feed opening also connecting with said tank, having for its object to enable the person filling the t-ank through the feed-opening by means ofthe sight-opening to `see when the tank is full, and to so prevent an overflow of oil.

Accompanying this specification, to form a part of it, there is a sheet of drawings containing three figures illustrating my invention, with the same designation of parts by letter-reference used in all of them. '0f these illustrations, Figure l is'an end elevation of an oil-stove containing my invention. Fig. 2 is a plan view of that part of the stove-base top which contains the feed-opening through which oil is supplied to tank, showing also the sight-opening. Fig. 3 is a section taken on the line a; w of Fig. 2, and somewhat enlarged.

The several parts of the stove and those containing my invention are designated by letterreference, and the function of the parts is described as follows:

The letter B indicates the stovebody, shown with one of its sides turned toward the sight.

The letter A designates the stove-base, the letter T the horizontal top of the latter, and N the oil tank or chamber, shown as placed beneath said base-top.

The letter D designates an offset made in the base-edge for the application of an Oilsupply opening, as shown and described in Letters Patent to J. F. Quimby, dated March 10, 1885.

The letter O designates a-feed-opening made in the top of the plate T and connecting with the tank N below the latter. The letter 02 designates a sight-opening,

also made in the said base-top adjacently to said feedopening. This sight-feed opening'is made with the sink S, the opening O2 being in the top thereof. It has a concave iuteriorsurface and is provided with a bottom opening, d, connecting with the oil-tank. This sink is extended downwardly into the tank, so that when oil is poured into said tank through the opening O it will rise in said sink so as to show the surface-level of the oil in the tank, the concave surface of the sink serving to con centrate the light upon the surface of the oil in the sink.

The letter C designates a cover attached to the upper surface of the base-top, constructed with a pivot, so as to swing in overV the facevopening and sight-openingto cover them, or

from over them to uncover them; i

While I have shown the sinkS .made with a concave surface, if desired, the sink may be made conical or in any other well-known form that will concentrate the light, upon the surface of the oil within the sink in the same manner. As thus arranged,the sightopening O2 provides independent means for indicatingy the rise of the oil in the tank while beingfilled through the adjacent feed-aperture.

Having thus described lmy invention, what I claim, a'nd desire to secure by Letters Patent,

The combination of the oil-stove-base top T, made with the sink S, having the top opening, Oand the bottom opening,d, and said top also made with the feed-opening O', and the tank N, arranged within said base, substantially as and for the purposes set forth.

Signed at Troy, New York, this` 7th day of January, 1886, and in the presence of the two witnesses whose names are hereto written.

GEORGE W; SWETT.
